Njirimara
A na-emepụta silicon carbide n'ụzọ abụọ:
1) silicon carbide na-enweghị nrụgide
Mgbe ihe na-enweghị nrụgide sintered silicon carbide etched, ihe osise kristal n'okpuru 200X anya mikroskopu na-egosi na nkesa na nha nke kristal bụ otu, na kristal kasị ukwuu anaghị agafe 10μm.
2) mmeghachi omume sintered silicon carbide
Mgbe mmeghachi omume sintered silicon carbide kemịkalụ na-emeso akụkụ dị larịị ma dị nro nke ihe ahụ, kristal
Nkesa na nha n'okpuru microscope anya 200X bụ otu, yana ọdịnaya silicon efu anaghị agafe 12%.
